Simplifying -16t2 + 40t + 125 = 0 Reorder the terms: 125 + 40t + -16t2 = 0 Solving 125 + 40t + -16t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by -16 the coefficient of the squared term: Divide each side by '-16'. -7.8125 + -2.5t + t2 = 0 Move the constant term to the right: Add '7.8125' to each side of the equation. -7.8125 + -2.5t + 7.8125 + t2 = 0 + 7.8125 Reorder the terms: -7.8125 + 7.8125 + -2.5t + t2 = 0 + 7.8125 Combine like terms: -7.8125 + 7.8125 = 0.0000 0.0000 + -2.5t + t2 = 0 + 7.8125 -2.5t + t2 = 0 + 7.8125 Combine like terms: 0 + 7.8125 = 7.8125 -2.5t + t2 = 7.8125 The t term is -2.5t. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5t + 1.5625 + t2 = 7.8125 + 1.5625 Reorder the terms: 1.5625 + -2.5t + t2 = 7.8125 + 1.5625 Combine like terms: 7.8125 + 1.5625 = 9.375 1.5625 + -2.5t + t2 = 9.375 Factor a perfect square on the left side: (t + -1.25)(t + -1.25) = 9.375 Calculate the square root of the right side: 3.061862178 Break this problem into two subproblems by setting (t + -1.25) equal to 3.061862178 and -3.061862178.Subproblem 1
t + -1.25 = 3.061862178 Simplifying t + -1.25 = 3.061862178 Reorder the terms: -1.25 + t = 3.061862178 Solving -1.25 + t = 3.061862178 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + t = 3.061862178 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + t = 3.061862178 + 1.25 t = 3.061862178 + 1.25 Combine like terms: 3.061862178 + 1.25 = 4.311862178 t = 4.311862178 Simplifying t = 4.311862178Subproblem 2
t + -1.25 = -3.061862178 Simplifying t + -1.25 = -3.061862178 Reorder the terms: -1.25 + t = -3.061862178 Solving -1.25 + t = -3.061862178 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + t = -3.061862178 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + t = -3.061862178 + 1.25 t = -3.061862178 + 1.25 Combine like terms: -3.061862178 + 1.25 = -1.811862178 t = -1.811862178 Simplifying t = -1.811862178Solution
